Home-Assistant
Introduction I have been experimenting with solar panels, Home Assistant and my electricity meter lately. This French meter from the utility is called Linky. It provides a small power supply (130 mW) and a serial link hidden via amplitude modulation.
To avoid using batteries, I built a prototype that harvests this power, demodulates the serial link, and feeds the data into an nRF52 development kit. It works well enough that I never bothered turning this messy setup into a proper PCB.
I recently did a proof of concept on shutters automation by hacking the remote
control: the idea is to wire the ESP in parallel with the remote control
buttons.
My remotes are Bubendorff 41677 but it should work with a lot of other remote
controls.
